A safety signal apparatus at a curved road using a solar battery is provided to reduce the consumption power by installing the vehicle traveling sensing sensor and only operating the apparatus when the vehicle is traveled. A safety signal apparatus at a curved road using a solar battery(20) is composed of a sensor part having first and second sensors(11,12) for sensing travel of vehicles(100a,100b); a power supply part for supplying the power to the apparatus; and guide parts(30a,30b) containing a first light source turned on only when the vehicle is traveled, a control part operated to turn on/off the light source by the signal of the sensors, a case where the first light source, a storage battery, and the control part are installed, a display plate attached at the front of the case to guide the traveling direction of the vehicle, and a flange for connecting the case and the display plate. The sensor part has third and fourth sensors(13,14) for sensing whether or not the vehicles are approached. |
